I guess it's plausible that the Laughing Place and lower half of the lift has some Friends on the Other Side stuff, and then Mama Odie shoo's them away when you reach the top. But I still don't think they'll bother even including any dark and scary elements in the ride at all...
Me either. I don’t believe for a moment there will be any conflict in the ride at all.
My guess at the storyboard:
“Tiana wants to make a special dish! But she doesn’t have the magic ingredient!”
Tiana: I’m so busy I could use your help finding the last ingredient! You guys go get it and I’ll check on you a couple times over the next 4 minutes!”
“Come on, handful of America Sings animals! Let’s help her find it!”
<insert original song about the hunt and how much fun it is>
<run into a couple characters from the movie who join in on the hunt and give advice on where to look. One of them suggests asking mama Odie>
<another song>
<something projection mapped, because that has to be in everything now>
“Mama Odie is just up that hill!”
<gopher pops out still informing you where he went to college>
<climb the hill>
“Mama Odie had the plant!”
“Ya’ll better hurry and get the plant to Tiana! She’s waiting at the restaurant! Fastest way there is down this hill!”
“By the way, this is a salt mine for some reason!”
<splash>
<final scene where Tiana has the plant and is serving the dish to her guests and probably a couple America Sings animals>
And generations of children are protected from asking what movie zip a dee doo dah was from. Mission accomplished.
